Abstract: In this paper, a negative polarity-based high-voltage linear power supply solution with optocoupler feedback is proposed, which can realize negative 1200V DC voltage output under the premise of using NPN type transistor as power regulating transistor. Furthermore, a small signal transfer function model is established for the proposed power scheme. Based on the transfer function model, it is proved that the proposed regulator has the advantages of high stability and low noise.

Key words: Negative high voltage, Low noise, Optocoupler, Wide load range, Linear regulator
